Abstract: Methods, systems, and devices for wireless communications are described that provide for configuration of channel bandwidth that may be specific to a particular user equipment (UE). A UE may be configured with a channel bandwidth that is less than or equal to a channel bandwidth of the serving base station, and may also be different than a channel bandwidth of one or more other UEs that are served by the base station. The base station may signal the UE-specific channel bandwidth in UE-specific signaling, such as UE-specific radio resource control (RRC) signaling.

Abstract: Methods, systems, and devices for wireless communication are described that provide for uplink common burst symbol waveform selection and configuration. A waveform for the uplink common burst symbol may be selected to be a single-carrier frequency division multiplexing (SC-FDM) waveform, an orthogonal frequency division multiplexing (OFDM) waveform, or combinations thereof, based at least in part on information that is to be transmitted. A pattern for SC-FDM sequences may be selected to provide enhanced channel estimation through common pilot tones across different sequences, wideband or narrowband sequences may be selected based at least in part on information to be transmitted, and acknowledgment feedback may be transmitted in an end portion of the uplink common burst symbol in some cases to provide additional processing time for determining the acknowledgment feedback.

Abstract: Wireless communications systems and methods related to decoupling uplink latency using common uplink (UL) burst in Time Division Duplex (TDD) sub-frame structure are disclosed. User equipment (UE) can transmit to a base station a common UL burst in each sub-frame communicated between UE and the base station, wherein he common UL burst comprises at least one of: a physical layer (PHY) acknowledgement (ACK), a scheduling request (SR), a buffer status report (BSR), or a sounding reference signal (SRS). UE can be further configured to transmit scheduled UL payload data in at least one common UL burst of at least one sub-frame communicated between the UE and the base station.

Abstract: Wireless communications systems, methods, and techniques related to signaling and determining slot and mini-slot structures are provided. A first wireless communication device transmits a first signal according to a first numerology including at least a first tone spacing. The first signal indicates a second numerology including at least a second tone spacing. The first wireless communication device transmits a second signal according to the second numerology. The first signal includes a physical broadcast channel (PBCH) signal. The second numerology is independent from the first numerology. Different slot/mini-slot structures may be utilized for varying channel types to support mixed numerology arrangements. Embodiments may utilize single and varied slot structures; single slot structures may be decoupled from transmission numerology and varied slot structures may be defined based on reference numerology. Other aspects, embodiments, and features are also claimed and described.

Abstract: A device obtains proof of its authority to use a first set of selectively activated features (first proof). An authorization server signs the first proof with its private key. The device sends a request to use a network service to a network node. The device sends the first proof to the network node. The network node validates the first proof using a public key of the authorization server. The network node grants the request to use the network service. The device sends a request for proof of authority for the network node to provide the network service (second proof). The device obtains the second proof, signed by another authorization server, and validates the second proof before using the network service. The first proof and the second proof each include a list of selectively activated features, where the selectively activated features are needed to use or provide the network service.

Abstract: The disclosure relates in some aspects to a scalable transmission time interval (TTI) and hybrid automatic repeat request (HARQ) design. The TTI is scalable to, for example, achieve latency and/or efficiency tradeoffs for different types of traffic (e.g., mission critical traffic versus traffic with more relaxed latency requirements). In the event a longer TTI is employed, various techniques are disclosed for ensuring a fast turn-around HARQ, thereby maintaining a high level of communication performance.

Abstract: A carrier recovery method and apparatus using multiple stages of carrier frequency recovery are disclosed. A receiver uses multiple frequency generation sources to generate carrier signals used to downconvert a received signal. An analog frequency reference having a wide frequency range and coarse frequency resolution is used in conjunction with a digital frequency reference having a narrow frequency range and fine frequency resolution. The multiple carrier signals are multiplied by a received signal to effect a multi-stage downconversion, resulting in a baseband signal. A frequency tracking module measures the residual frequency error present in the baseband signal. The measured residual frequency error is then used to adjust the frequencies of the carrier signals generated by the multiple frequency generation sources.

Abstract: Techniques for selecting either a DFE or an LE for use to equalize a received signal, and for quickly and efficiently determining the coefficients for the selected equalizer. In an embodiment, a method is provided whereby the DFE is initially adapted based on the received signal and a particular adaptive algorithm (e.g., the LMS algorithm) for an initial time period. A quality metric is then determined for an output of the DFE. The DFE is selected for use if the quality metric is better than a threshold value, and the LE is selected otherwise. If the LE is selected, then the initial values for the coefficients of the LE may be derived based on the coefficients of a feed-forward filter and a feedback filter for the DFE, and the LE coefficients may further be adapted for an additional time period prior to its use to equalize the received signal.
